New description:
{{{
sage: G = Graph({1:[2,3,4]})
sage: sage.graphs.graph_plot.DEFAULT_PLOT_OPTIONS['vertex_shape'] = 's'
---------------------------------------------------------------------------
AttributeError Traceback (most recent call
last)
<ipython-input-2-aa626427af43> in <module>()
----> 1 sage.graphs.graph_plot.DEFAULT_PLOT_OPTIONS['vertex_shape'] = 's'
AttributeError: 'module' object has no attribute 'graph_plot'
sage: G.plot()
Launched png viewer for Graphics object consisting of 8 graphics
primitives
sage: sage.graphs.graph_plot.DEFAULT_PLOT_OPTIONS['vertex_shape'] = 's'
sage:
}}}
I.e. I can set up default options for graph plotting, but only after
making at least one plot.
Also this might relate to
{{{
sage.graphs.graph_plot.DEFAULT_SHOW_OPTIONS['vertex_shape'] = 's'
G.show()
}}}
--> `TypeError: matplotlib() got an unexpected keyword argument
'vertex_shape'`. It seems that default options for **show** does not work
at all.
